A decentralised ledger engineered for Advanced Banking.
AvatarPay's core infrastructure combines a high-performance smart contract ledger, programmable smart contracts, and an automated tax engine - all on the same immutable record. No syncing lag. No reconciliation errors. No settlement delay.
Outgoing payment
SettledBuilt on a decentralised, real-time ledger.
Every transaction is encrypted, tamper-evident, chained, and shared across multiple nodes - providing a single source of truth with no central point of failure.
Immutability
Once a transaction is recorded on the AvatarPay ledger, it cannot be altered or deleted. A tamper-proof audit trail - the foundation of trust in an Advanced Banking system.
Real-time processing
Unlike legacy systems that rely on overnight batch processing, the decentralised ledger updates instantly. Real-time fraud detection and always-accurate balance reporting are inherent - not add-ons.
Byzantine fault tolerance
The decentralised network means that even if some nodes are compromised, the integrity of the overall ledger remains intact. No single point of failure.
Smart contract logic
Financial product behaviour - interest, fees, eligibility - is written directly into on-chain contracts. Payments execute only when every defined condition is verifiably satisfied.
Throughput that meets and exceeds legacy benchmarks.
AvatarPay's smart contract infrastructure targets performance levels that surpass existing benchmarks - while adding verifiable security legacy systems cannot offer.
| Metric | Legacy core banking | AvatarPay (target) |
|---|---|---|
| Transactions per second | 100–500 | 50,000+ |
| Settlement time | Hours to days | Sub-second |
| Data structure | Relational database | Tamper-evident chained blocks |
| Security model | Centralised firewall | Decentralised consensus |
| Audit trail | Mutable, batch-processed | Immutable, append-only, real-time |
Legacy figures based on published industry benchmarks. AvatarPay targets achieved via L2/sidechain architecture.
Invoice fraud is a multi-billion-pound problem legacy banking has not solved.
Fraudsters use business email compromise to intercept legitimate invoices and replace bank details with their own. Traditional UK payments rely on static sort codes and account numbers - a system where authorisation and settlement are asynchronous, leaving a window for error, fraud, and reconciliation gaps.
Authorised Push Payment fraud exploits this lag. Once funds leave the account, reclaim is lengthy and uncertain. Existing Confirmation of Payee systems lean on centralised databases and human intervention - the underlying ledger is not deterministic.
AvatarPay moves to a Zero-Trust Banking Architecture where every payment is verified on-chain before funds move. The code enforces the rules.
Accounts that act - not just record.
In traditional banking, an account is a passive ledger. In AvatarPay, accounts are programmable agents governed by smart contracts - self-executing protocols where the terms of every transaction are written directly into code.
Using if-this-then-that logic, a payment can be made contingent upon decentralised verification. A transaction is blocked unless the recipient's verified signature matches a verified identity on the smart contract ledger.
This eliminates the "wrong payment" scenario at the architectural level. Smart contracts are the deterministic arbiters.
Recipient's verified signature must match their on-chain identity (DID).
AvatarPay performs decentralised verification of the recipient's public key across the consensus network.
→ Transaction authorised and settled in sub-seconds. Immutable record written to the ledger.
→ System refuses to authorise. Tampered invoice detected, payment blocked, sender notified.
Every payment, verified on-chain.
A glimpse of the AvatarPay consensus network in motion. Tampered DCIs are refused before funds move - settlement is final and immutable.
